The conductivity of pyrrolidinium and sulfonylimide-based ionic liquids:A combined experimental and computational study

摘要

Ionic conductivity is a fundamental property of ionic liquids with its origin and exact nature under debate. Using a specially selected system of pyrrolidinium cations (PYR_(1x),x = 3,4)and sulfonylimide anions(FSI, TFS1, BETI.and lM14)-based ionic liquids we observe a simple and accurate connection between ab initio computed cation and anion volumes and measured molar ionic conductivities.
